Tunnels and underground structures

GEOS’ work in the field of underground structures covers new structures and those to be rehabilitated – tunnels, galleries, open and covered trenches, shafts, underground stations, collectors, avalanche barriers – in all sectors: roads, motorways, railways, high-speed lines, hydraulic projects, car parks, mines, and for a wide variety of clients: the state, local authorities, motorway concessionaires, public establishments and private companies.

GEOS has expertise in geonumerical and geotechnical modelling and calculations. Using high-performance 2D and 3D software, the modelling of underground structures takes into account complex behaviour laws, construction phases and soil-structure interaction in order to optimise design.
